This ‘Iron Man 2’  footage was originally shown last month during the Marvel Panel at Comic Con in San Diego and  was introduced by actor Robert Downey Jr. Someone quietly recorded the video and has posted it on YouTube. Director Jon Favreau tweeted, “Thanks for all the encouraging feedback. Will let you know if/when official clean version goes up.”  The whole cast looks great and the footage of Whiplash and War Machine  will blow you away! Watch it quick before the powers-to-be, Paramount, take it down!
